SkyKingII Posted April 15, 2021 Share Posted April 15, 2021 Does anyone have a suggestion on lubricating the air chuck(female part) that sets beside the Onan 7.5 ,as to what to use ie silicone,dry lube etc. It is getting very difficukt to insert and release.Once it connects ,no leaks etc ...just difficult to manuver.These hands are getting old! Thanks in advance for quick advise.It is still the original chuck. Bruce Crocker 2004Diplomat 40'PDQ Link to comment Share on other sites More sharing options...
klcdenver Posted April 15, 2021 Share Posted April 15, 2021 Change it out the rubber gasket in it is old and getting hard which makes it hard to insert the male fitting into it. Link to comment Share on other sites More sharing options...
ncsteve Posted April 15, 2021 Share Posted April 15, 2021 WD40. Link to comment Share on other sites More sharing options...
DavidL Posted April 15, 2021 Share Posted April 15, 2021 Replace it. With a good quality Milton or better. Lot of junkie air fittings around. BTW...what do you use it for? inflating tires? It's original purpose is for airing up during a tow....you can't possibly be getting towed that often! Link to comment Share on other sites More sharing options...
SkyKingII Posted April 16, 2021 Author Share Posted April 16, 2021 Thanks for replies...I concidered wd40 but was concerned with it attracts and holds debris possiblyadding to problem,but if you guys have used it w/o incident it obviousky is ok. I'm guessing kLcdenver's suggestion is probably the permanant fix ...I just was hoping to just squirt it and go! Will do a quality one and be done with it ,I was thinking the rubber was the culprit also.BTW David yes I use it for airing up tires ...so far in 15years haven't had a tow...wanna keep it that way! Thank you all for the input. Bruce Crocker 2004 Diplomat 40'PDQ Link to comment Share on other sites More sharing options...
bobdinsmore Posted April 16, 2021 Share Posted April 16, 2021 If the WD40 doesn't work as easy as you want/need, feather the air brake to drop the pressure way down and you will be able to connect the hose. I learned this thru the air tools I use at home. Link to comment Share on other sites More sharing options...
cbr046 Posted April 16, 2021 Share Posted April 16, 2021 Keep in mind WD-40 is NOT A LUBRICANT. Never was, never will be. If anything I'd try some silicone spray as it won't attract dirt like oil will. Best, - bob (NOT a petroleum engineer) Link to comment Share on other sites More sharing options...
